lLLUMlNANT ATTACHMENT FOR HEAD-MIRRORS AND LARYNGOSCOPES.

SPECIFICATION forming part of Letters Patent No. 769,420, datedSeptember 6, 1904. Application filed February 17, 1904- Serial No.193,969- (No model.)

To (Y/ZZ whom it may concern: ,I

Be it known that I, ALFRED F. WA'roH, a citizen of the United States,residing at Philadelphia,county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in IlluminantAttachments for Head-h Iirrors and Laryngoscopes, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, which form a part of this specification.

The illumination for reflectors or head-mirrors has heretofore beenderived from lamps or other sources of illumination apart and separatedfrom the head mirrors or reflectors. This has been inconvenient in thatthe reflected illumination has been in the line of vision at only onerelative position of headmirror and the source of light, necessitating ashifting 0r adjustment of one or both when the head and eyes of theoperator are turned toward another part of the subject operated upon,some improvements to overcome these inconveniences by condensing-lenseshaving been attempted with small success.

The object of my invention relates to certain improved illuminantattachments for head mirrors or reflectors, so that the lightrays areretained in the line of vision in whatever direction the turned.

I will first describe the embodiment of my invention illustrated in theaccompanying drawings and then point out the invention .in the claims.

In the drawings, Figure l is a side view of my invention with the mirrorand reflector in section. Fig, 2 is a plan View with the reflectorturned to the operative position. \Fig. 3 is a detail section on theline 3 3, Fig. 1.

A is the head-band, offwell-known construction. This head-band" isconnected to the ball a, secured between frames a, operated andsupported by the clamping-screw a a. is a ball secured by projection ato the angular frame 6, to which is connected the head-mirror B, havingthe aperture 6 Swiveled on the frame 5 and adapted to be secured'theretoby the thumb-screw 0 is the rod C. Mountedupon this red, so as to behead. of the operator be movable longitudinally and rotating thereon,

is the framed, to which, by means of the angle-frame (Z', is secured thereflector l), the frame (.Z being secured to frame (I by means of thescrew upon which it is adapted to swivel. The reflector D may beparabolic, spherical, hyperbolic, or plane, as the purpose may require.

E is a frame secured to the rod 0 so as to bemovable longitudinally androtating thereon and is secured thereto by means of the thumb-screw a.

f is a rod passing through the lower end of frame E and carrying theelectric-light socket f and binding-postf and light-bulb F, projectingthrough an opening in the reflector. This rod f is secured to the frameE by the thumb-screw f G is a flexible strip of conductive materialconnected to and insulated from and having the binding-postc. One wirefrom a source of current-supply (not shown) is connected to binding-postf and the other wire from said source of current-supply is connected tothe binding-post a.

When the instrument is in use, the rod (3 is.

turned into the required angle to the plane of the mirror, as shown inFig. 2, so that the reflector Dis out of line of vision through theaperture 6 to the subject. The point of light when parallel rays aredesired is placed in the focus of the parabolic reflector, whence theyare reflected to the surface of the head-mirror B, which may be plane orof such curvature as to focus the reflected rays at any desiredrpointeven though the point of light be inside of the focal distance of aconcave mirror, the rod G being, after proper adjustment, securelyclamped to the frame I), which being rigidly or fixedly connected 'tothe mirror B light and mirror to each other in whatever position theymay be turned by the head of the operator acting on the head-bar A, uponwh'ch the whole apparatus is carried.

he reflector when properly constructed and adjusted screens the, eye ofthe operator as well asthe subject from direct illumination.

The reflector and-lamp-support are capable of adjustment along and withreference to the IOC . maintains the relative position of thereflectorrod by the construction herei'nbefore -de.- "scribed. d/ I donot intend to limit myself to the etails of construction hereinbeforeset out ex "5 cept as the same may be specifically claimed, as thesedetails may be varied from in many ways in an embodiment of myinvention. I believe myself to be the first to liave'constructed aself-contained apparatus comprisminant so arranged as to maintain aconstant relative position of the mirror, reflector, and illuminant withthe line of vision through the aperture inthe mirror unimpeded in anypo- 1 5 sition the operator through the head-band may turn theapparatus. a

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is-

\ 1. In an apparatus of. scribed, in combination,-an apertured mirror,a'reflector,. an illuminating device, and a device connected to saidmirror, adapted tobe swung at an angle to said mirror, supporting saidreflector and illuminating device. p 2. In an apparatus of the characterdescribed, in combination, anaperture'd mirror,
